On 05 August 2007, 24 year old Mark Beaumont from Fife, set off from the Champs Elysees in Paris in his attempt to smash the current record for circumnavigating the globe by bicycle.
To follow Mark's journey, BBC Scotland produced a TV documentary which you can watch from 18 August.
Mark (or 'Monty' as he's known to his friends) was almost born on two wheels. Aged 12 he cycled across Scotland from Dundee to Oban (raising £2,000 for charity).
Two years later he bought his first road bike and then aged 15 did the classic 'End to End' journey, riding from Land's End to John O'Groats (raising £3,000 for charity).
After high school he then helped raise £50,000 for the Erskine Hospital for Ex-Servicemen and Women by cycling the 1,334 miles from Sicily to Innsbruck in Austria up the length of Italy.
During university, however, Mark started to get an itch for 'a big one' and you can't get much bigger than circumnavigating the globe! After graduating, he went to work for a few months but the thought wouldn't go away. So despite people telling him that he'd need longer than six months to plan and train for something of this size, he left his job and threw himself into it.
Luckily, everything fell into place and with a great team behind him (including sports scientists, nutritionists and, of course, the BBC!) he eventually set off from Paris on 05 August 2007.
All in all, Mark travelled 18,000 miles and smashed the existing record of 276 days by a whopping 82 days.
